JOHN IVILS ON, OF NEW YORK, N. Y., ASSIGNOR TO THE AMERICAN AOE'IIG ACIDCOMPANY, OF JERSEY CITY, NEIV JERSEY.

CLAMP FOR WOOD-SAWING MACHINES.

SPECIFICATION forming part of Letters Patent No. 375,909. dated January3, 1888.

Application filed June 30,1887. Serial No. 243.030. (No model.)

To aZZ whom, it may concern:

Be itknown that I, JOHN VVILsN,acitizen of the United States, residingat New York city, in the county of New York and State of New York, haveinvented certain new and useful Improvements in Clamps for VVootLSawingMachines; and I do declare the following to be a full, clear, and exactdescription of the in vention,such as will enable others skilled [O inthe art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to the letters andiigures ofreference marked thereon, which form a part of this specification.

My invention consists of an improved clam p device for holding wood onthe feedingiable of a cuttingoff sawingmachine of any kind, but moreparticularly such as consist of a gang of circular saws employed forcutting bundles of sticks into short lengths for kindling-wood, ashereinafter fully described,

reference being made to the accompanying drawings, in which- Figure 1 isa side elevation of a sawing- 2, machine provided with my improved clampdevice, and Fig. 2 is a plan view of the same. The bench a, saws b, andfeed carriage 0 may be of any ordinary contrivauce.

My improved clamp consists of a strong 0 wire, (I, having a loop or eye,0, in each end, the hook or an eye, f, on the back part of the carriage,and the ratchet-lever g at the front edge of the carriage, the clamp-wire being connected by one end to the ratchet-iever and by the otherend to the hook or eyef, and one of said connections, and preferably thelatter, being detachable, so that when the pile of wood, It, to be sawedhas been duly arranged on the carriage it may be bound fast by hookingon the clamp-wire atf and then straining the wire tight and making itfast by the lever g, pawl h, and ratchet i, the lever with its pawlbeing free to turn, but the ratchet being stationary. Thus I provide aclamp of very sim- 5 ple eontrivance, by which a bundle of sticks may beheld as immovably as one stick, the clamp being adapted for beingapplied and operated with but very little hinderance or delay to thework. It is especially adapted for use in gang sawing machines, wherethe out pieces must be held intact between the saws while beingwithdrawn therefrom to be discharged. In such machines a clamp will beemployed between each two of the saws, and there may be one at eachouter extremity of the gang, if preferred. \Vhen employed in agangmachine, the levers and the ratchets are preferably mounted on a shaft,j, that is suitably attached to the front of the carriage, the leversbeing fitted to turn freely on the shaft, the ratchets being keyed orotherwise made fast to the shaft, and the shaft attached so thatit willuotturn; but any other arrangement may be employed.

Although I have described and represented the pawl-lever and pawl as thecontrivance for straining and fastening the clamp-wire I do not mean tobelimited to that alone, for it will be readily understood that othercontrivances may be employed-as a spring that may be stretched with alever and hooked onto the clamped wire and then be let free to recoiland draw the wire tight; nor do I mean to be 1i mited to wire clamps, ascords, chains,or straps of leather may be used.

What I claim,and desire to seeureby Letters Patent, is

1. The combination of the clamp-wire and clamping -lever, pawl, andratchet with the feed-table of a sawing machine, the clamp- 8) wirebeing detachably connected at one end, substantially as described.

2. The combination, with the saws and feed table of a gangsawing-machine, of a woodholding clamp between each two of the saws,consisting of the clampwvire and clamping-lever, pawl, and ratchet, theclamp-wire being det-achably connected at one end, substantially asdescribed.

In testimony whereofIalfiX my signature in presence of two witnesses.

JOHN \VILSON.
